The groom, meanwhile, had just one job – driving his bride from the ceremony at the church to their reception venue, a 17th-century house in Cheshire where 61 guests dined on sausage and mash, Laura and Jason’s favourite dinner.

“Jason wanted 10 minutes [for] just us two straight after the wedding,” says Laura.

“He told me he wanted to get an old-style car so when [I saw it] I was like: ‘What is that?’ There, at the back of the church was this bright green Lamborghini!”

With another two golds to her name from London 2012, she is now Britain’s most successful female competitor in any sport.

Success, however, brings a heavy weight of public expectation, which Laura struggles with.

“Trying to get back into it with the pressures and everything that the Games in London 2012 brought for me – people expecting you to win – was hard. I was only 20. I don’t think I would have quit, but I did stop enjoying it for a time.”

She admits that pre-race anxiety is her biggest weakness and she suffers so badly that she “can throw up with nerves”.

“There wasn’t a Sir Bradley Wiggins or a Victoria Pendleton and the so-called cool kids used to shout at me because I’d be wearing a helmet. Girls drop out of sport because they don’t feel feminine. I can have really long hair and wedge it under my helmet and show them that it can be done.

“I haven’t got the biggest boobs in the world and I would rather have the thighs that I’ve got than be unhealthy and really skinny because of it. It’s about acceptance. Embrace what you’ve been given.”

National champion at 12, Laura was on the Olympic Development Programme by 15 and competing in her first Commonwealth Games in Delhi three years later alongside her sister Emma, now 26, who also used to cycle professionally.

So it was perhaps inevitable that Laura would end up representing Great Britain at London 2012.

Success, of course, requires dedication.

Laura trains six days a week, riding her bike for up to four hours at a time.

Her immediate future is undoubtedly exciting.

Laura and Jason have released a book together, The Inside Track, plus there’s a host of endorsement offers on the table.

Next month, she will race at the Senior National Madison Championships and then, fitness levels depending, take on next year’s World Championships.

Jessica Ennis-Hill has also helped her realise she can juggle her career and be a mum.

“Until Jess did what she did, I never thought that having kids and being a sports person was even possible,” says Laura.

So how would she feel if she discovered she was pregnant?

“I’d be happy because I’ve always wanted kids. I’d just deal with it,” she says.

As for Tokyo 2020, Laura hopes to be selected, but knows she can never rest on her laurels.

“Just because I’m Olympic champion now doesn’t mean I’m going to be good in four years. Every time I step on that podium I think: ‘How did I get here?’ Because for me it’s not a job, it’s just fun, which makes me so lucky.”Laura Trott and Jason Kenny: The Inside Track is out now (£20, Michael O’Mara).

“The cashier said: ‘You’re that girl who kicks people in the head!’ I’m recognised a lot more since Rio,” says Jade, whose nickname – The Headhunter – was born from the way she targets opponents’ heads rather than their bodies.
